View of ISS Crossing the Sun During an Eclipse

Photographer Thierry Legault shot what may be the coolest view yet of the today’s solar eclipse: the International Space Station’s weird little silhouette flying across a thin sliver of visible sun.

A way to explore Venus

NASA Langley researchers want to get a better idea about conditions on our nearest planetary neighbor, Venus, so they have come up with HAVOC or a High Altitude Venus Operational Concept – a lighter-than-air rocket ship that would help send two astronauts on a 30-day mission to explore the planet’s atmosphere. Exploration of Venus is a challenge not only because its smog-like sulfuric acid-laced atmosphere, but also its extremely hot surface temperature and extremely high air pressure on the surface.

It’s quite awesome really, many of them just get eaten by Jupiter and are never seen again. The rest usually get catapulted back into space by Jupiter’s immense gravity. It’s quite amazing just how many things are keeping Earth alive and the way it is.

THANK U VERY MUCH JUPITER

Jupiter ‘shepherds’ the asteroid belt for us

I think this is proof enough to tell us that the life we have now is a result of an uncountable number of coincidences,

Imagine a AU where something as crucial as this is not happening, life would be much different.

Numbers are ∆v required to transfer orbits
White arrows indicate inbound aerobraking available
All transfers are assumed to be Hohmann transfers with burns performed at periapsis (for maximum use of the Oberth effect)
Gravity assis and other manoeuvres may reduce ∆v requirements.

Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretch 4 billion light-years from end to end. The structure is a light quasar group (LQG), a collection of extremely luminous Galactic Nulcei powered by supermassive central black holes.

So that’s cool and everything, but maybe some of you would be interested to know why this is a significant find? Beyond just its record-setting bigness.

Since Einstein, physicists have accepted something called the Cosmological Principle, which states that the universe looks the same everywhere if you view it on a large enough scale. You might find some weird shit over here, and some other freaky shit over there, but if you pull back the camera far enough, you’ll find that same weird and/or freaky shit cropping up over and over again in a fairly regular distribution. This is because the universe is (probably) infinite in size and (we are pretty darn sure) has, and has always had, the same forces acting on it everywhere.

So why is this new LQG so radical? (It stands for ‘Large Quasar Group,’ btw, not ‘Light Quasar Group.’)

Well, let’s try to comprehend the scale we’re dealing with. A ‘megaparsec,’ written Mpc, is about 3.2 million light years long. The Milky Way is about 0.03 Mpc across (or 100,000 light years). The distance between our galaxy and Andromeda, our closest galactic neighbor, is 0.75 Mpc, or 2.5 million light years. LQGs are usually about 200 Mpc across. Assuming a logarithmic distribution of weird shit outliers (if you don’t know how logarithmic distribution curves work, don’t worry about it), cosmologists predicted that nothing in the universe should be more than 370 Mpc across.

This new LQG is 1200 Mpc long. That’s four billion light years. Four BILLION LIGHT YEARS. Just to travel from one side to the other of this one thing. I mean for fuck’s sake, the universe is only about 14 billion years old! How many of these things could there be? 

Right now it looks like the Cosmological Principle might be out the window, unless physicists can find some way to make the existence of this new LQG work with the math (and boy, are they trying). And that’s totally baffling. It would mean—well, we don’t have any idea what it would mean. That the universe isn’t essentially uniform? That some ‘special’ physics apply/applied in some places but not in others? That Something Happened that is totally outside our current ability to understand or quantify stuff happening?

By the way, no one lives there. The radiation from so many quasars would sterilize rock.

are you telling us astronomers have discovered something which is literally fucktuple the size of anything else previously estimated to exist
